Aircraft Weight and Balance

iOS Universal

The Aircraft Weight and Balance app is based on the FAA’s Aircraft Weight and Balance Handbook. The app explains the importance ofweight and balance technology in conducting safe andefficient flight. The objective of this handbook is twofold:to provide the Airframe and Powerplant Mechanic (A&P)with the method of determining the empty weight andempty-weight center of gravity (EWCG) of an aircraft,and to furnish the flightcrew with information on loadingand operating the aircraft to ensure its weight is within theallowable limit and the center of gravity (CG) is within theallowable range.

This app begins with the basic principle of aircraftweight and balance control, emphasizing its importanceand including examples of documentation furnished by theaircraft manufacturer and by the FAA to ensure the aircraftweight and balance records contain the proper data.

Procedures for the preparation and the actual weighingof an aircraft are described, as are the methods ofdetermining the location of the empty-weight center ofgravity (EWCG) relative to both the datum and the meanaerodynamic chord (MAC).

Loading computations for general aviation aircraft arediscussed, using both loading graphs and tables of weightand moment indexes.

Information is included that allows an A&P mechanic orrepairman to determine the weight and center of gravity (CG)changes caused by repairs and alterations. This includesinstructions for conducting adverse-loaded CG checks, alsoexplaining the way to determine the amount and location ofballast needed to bring the CG within allowable limits.

The unique requirements for helicopter weight and balancecontrol are discussed, including the determination oflateral CG and the way both lateral and longitudinal CGchange as fuel is consumed.

A chapter is included giving the methods and examplesof solving weight and balance problems, using handheldelectronic calculators, E6-B flight computers, and adedicated electronic flight computer.

We have also included a chapter with functioning calculators to assist in your understanding of weight and balance calculations.
